Prerequisites

The student should be familiar with basic Physics knowledge, especially the topics related to forces or energies. These topics are covered in the secondary school courses  If the student has never studied them it would be good to do the propedéutic course of Physics for Biosciences. it is also recommended at least to read a high secondary grade textbook including them.

Physical concepts like electromagnetic fields and waves, although important, are not required because they are introduced again during the course.


Objectives and Contextualisation

Because of its fundamental nature, knowledge in physics is very often a necessary tool for the correct understanding of the phenomena described in other sciences. In the specific case of Biotechnology, for example, to correctly understand the dynamics of chemical reactions within cells, it is completely indispensable to know the physics of diffusion, the field and electrical current or thermodynamics. Without this knowledge a misunderstanding of the biochemistry of the cell is possible.

On the other hand, Physics is required to understand some of the experimental methods that biochemists use daily. In our case, for example, radioactive or fluoescent marking of molecules, centrifugation or magnetic resonance are examples of methods that are clearly based on fundamental physical principles.

The objective of this subject will be the introductory study of all the necessary physical concepts for both, modeling and experimental design in Biochemistry.

Some of the topics will be the starting point of other courses such as Thermodynamics, Bioenergetics and other topics will be fundamental for the practices included in Integrated Laboratories.

The subject will be given alternating different types of methodologies:

- Master classes where the general concepts of the different topics will be introduced

- Solving problems  where the teachers will solve the exercises previously selected in previous days

- Practices where questions will be proposed where Physics is related to biosciences and where the student will have to solve certain questions in a group

- Resolution of autocorrection questionnaires through a computer using the Moodle platform

- Reading of didactic material in biosciences where physical concepts are applicable

- Experimental practices at home.

Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.


Assessment

Continous Assessment Activities

Title Weighting Hours ECTS Learning Outcomes
Computer assisted practices 20$ 30 1.2 CM04, CM05, SM05, SM06
Exams 80% 4 0.16 CM04, CM05, CM06, KM04, KM05, KM06, SM04, SM05, SM06

         

Ordinary assessment:

The assessment is composed of two mid-term tests and a set of online practices. The weighting of each partial test will be around 40% each. These weights may vary slightly depending on the amount of topics contained in each one. The rest of the mark (20%) will come from the marks obtained in the practices carried out during the course. The student must obtain a grade higher than 3.5 in the partial tests so that he can perform the average with the practices. If this grade is not obtained, the final grade will not be approved even if the overall average is greater than 5.

Recovery exam:

At the end of the semester there will be a second exam for each of the partial tests. This will be for all those students who have not passed the ordinary tests or who want to improve their grade. If a student takes one of these make-up tests, they will forfeit the grade obtained in the regular part test. The final grade will be calculated as in the ordinary assessment with the make-up marks replacing the previous ones. To participate in this exam, students must have previously been assessed in a set of activities with a weight of at least two thirds of the subject. Students will receive a grade of "Not Assessed" when the assessment activities performed have a weighting of less than 67% in the final grade.
